This. invention relates t`o timber "setting machines, and moreparticularly to an improved'm'achine-for setting mine timberingelements, such as horizontal cross timbers, in an underground mine ortunnel.

In underground mining or tunneling, horizontal cross 'timbers are placedagainst the roof as the Work advances, and the cross timbers are Aset inposition by uprights or props, or by rib pinnings. Such setting ofthecross timbers is usually effected manually.. and is an extremelyhazardous, arduous and time-consuming task. Also, the timbers and propsmust be transported long distancesin the mine or tunnel. Machines havepreviously been vemployed for mechanically setting the cross timbers,but'such machines are limited in operating range, are relatively 'highand bulky, and do not havesulicienttimber and prop carrying capacity ormust carry the 'timbers and props on's'eparate trailers. The'presentinvention contemplates improvements 4over such known machines in thatextreme compactness is 'attained while' providing a relatively largetimber vand prop carrying capacity Within the ,machine'itsell and also arelatively wide range of operation and in- -vcreased flexibility areobtained. By the provision of 'such a machine, the cross timbers Yaremoved Vup against the mine or tunnel roof and firmly held there duringsetting of the timbers'thereby makingythe task of timber settingrelatively easyand 'minimizing the danger.

It is accordingly an object of the present invention to provide animproved timber setting machine whereby ,the disadvantages of previousmachines are substantially overcome. Another 0bject is to provide animproved timber setting machine having, within itself, a'relative'lylarge timberandprop carrying capacity. Yetanother object is toprovide animproved timber settingmachine 'having a relatively wide operatingrange.A .further object is to provide an improved adjustable timber supportingstructure for'receiving and supporting across timber and forelevatingthetimber to bring the latter up against the roo'f and yfor :holding itthere during setting thereof. A still further object is to provideal1-improved `timber setting machine having a machine body .providedwith arelativelyflarge'timber andprop carrying compartment arranged in arelatively 10W positionand of substantialvvidth andheight Wherebvarelatively vlarge `number of Jmine timbers and props Lean beytransported'While smaintaining Athe-overall height of the-'machinerelativelylow, thereby enabling Ithe-machine to 'operateinminesor-tunnels having-relatively-lowi head 4vlarge loadcan becarriedjbut also 'affording arelatively Wide .range of adjustment.' Afurther object is to provide an improved Vadjustable supportingstructure mounted on .'themachine body vfor horizontal adjustmentwherebytimbersmay `be supported ateither `side of the machine'body aswell as crosswise'at one 'end ofthemachine body.y Still another objectis to provide'improved adjustable timber guides for .guiding the timbersloading of the bo'dyecompartment and 'for `directing a timber fromthe-'compartment 'onto the' turntable or saddle of the adjustable'timbersupport.

A still further objectis'to provide an improved extensible elevatingjack structure for supporting and elevating a timber, together withafloor-engaging vjack for holding the parts iirmly in position duringoperation'thereof. It is a `:further object to provide animproved'timber setting machine having an improvedarrangement 'andcombination of parts. These and other lobjects and advantages oftheinvention will, hovvever,here

In the illustrative embodiment of the invention, as shown in thedrawings, the improved. timber setting machine is preferably of therubber tired, wheel mounted type especially designed for use in settingroof timbers or cross barsiiitrackless mines or tunnels. Evidently, themachine may be mounted in other manners and used for other purposes.VThe machine comprises a low compact body l mounted on rubber tiredwheels adapted to travel over the floor of a mine 'or tunnel, and therear wheels 2, 2 are traction wheels and are driven by suitable motors,preferably electric motors, 3, 3 through suitable transmissionconnections e, fi. The front wheels 5, are steering wheels and areswiveled in a conventional manner to turn horizontally and are providedwith suitable iiuid operated steering gear controlled by a hand wheel 6located in a recess providing the operators station at one side of theiront end of the machine body. A motor l, likewise preferably anelectric motor, drives a pump to be later described. Extending centrallylengthwise of the machine body is a timber carrying compartment S ofsubstantial width and height. Mounted on the machine body beneath thecompartment for swinging on a vertical axis and extending outwardlybeyond the rear end of the body is a horizontal support 9 carrying, atits cuter extremity, an elevating jack structure I9 which supports ahorizontal timber receiving support or saddle il. rihe load carryingcompartment 8 is adapted to receive a load of mine timbering elementssuch as cross timbers and props, and a guide roller device l2 isarranged at the front end of the compartment for facilitating loading oftimbers. When the support or saddle is properly positioned, a timber maybe moved lengthwise from the compartment over .a rear guide rollerdevice l2 onto the support. The jack l may be operated slightly to raisethe saddle above the top of the machine body and the timber may then beturned with the saddle into a position crosswise of the machine body atthe rear or the latter. The jack i0 may then be operated to elevate thesaddle to bring the timber up against the roof and to hold it thereduring setting -of the uprights or props, or during insertion of the ribpins. Arranged in a recess at the opposite side or the front end of themachine from the operators station is a conventional cable reelmechanism i3 for the power conductor cable through which power isconducted to the electric motors 3, 3 and l; and this reel is driven inwinding direction by a conventional hydraulic motor I3. At one side ofthe rear end of the machine body is an electrical control apparatus I4for the electric motors, while at the opposite side of the real) elfld.0f the l 3G at its rear end to the lever 2l.

body is a power saw i5, driven by a hydraulic motor l5. The' tractionwheel and pump driving motors, the steering mechanism, the cable reelmechanism, electrical control apparatus and the power saw may be similarto those fully described in a copending application to C. F. Ball etal., Serial No. 746,646, filed May 8, 194'?.

' The machine body is preferably of a fabricated, welded constructionand has vertical plates l1, l1 extending longitudinally of and spacedequi-distantly from the longitudinal center of the machine body, andthese plates` iorm the sides of the load carrying compartment 8. Thecompartment bottom is formed by a bottom plate 1 8, so positioned thatthe compartment bottom is in a relatively low position below ahorizontal plane'including the wheel axes, and the wheel axles, whichare herein drop axles, extend transversely beneath this bottom plate.The horizontal swinging support t is herein preferably in theform of abell crank with one `arm El) projecting rearwardly from the machine bodyand at its outer end supporting the extensible jack structure, and thisarm has a forward bearing support 2i swiveled on a vertical pivot shaft22 suitably secured to the bottom plate i3 midwal7 between the platesil, at the longitudinal vertical center of the machine. Projectinglaterally from one side of the bearing sup-port 2| at substantiallyright angles to the arm 2S is a shorter arm 23 to which the rear end ofa link 2d is pivotally connected at 25. This link extends longitudinallyforwardly beneath/the compartment bottom and is pivotally connected at25 at its front end to one end of a lever 2l, the latter in turnpivotally mounted at 23 on a bracket 29 suitably secured to the adjacentside plate il. Secured to a cross plate 3@ integral with the machinebody is a bracket 3l to which is pivoted, at 32, a horizontal iuidcylinder 33, also located beneath the compartment bottom. Reciprocablein this cylinder is a piston 34 having its piston rod 35 projectingrearwardly through the packed rear cylinder head and pivotally connectedat Thus, when the piston is moved in the fluid cylinder, the rearwardlyprojecting arm 2i? may be swung through the lever 2, link 2d and arm 23horizontally from one side of the machine body to the other, and thelower rearward portions of the plates Il are cut away at 3i to permit awide range of horizontal swing, to locate the saddle beyond the sides ofthe machine body. The machine body has a horizontal rearward projection38 l having .a rearward arcuate end 39, and the arm 23 has a verticalportion c@ which supports upper and lower projections Il! and 42, whichrespectively overlie and underlie the curved end 39 of projection 3.8for guiding the arm during horizontal swinging thereof and to provide arearward arm support. The timber elevating jack lil, carried at theouter extremity o the horizontal arm 253, may assume various forms andherein comprises a vertical uid cylinder i5 having a flange 46 secured,as by screws, to the upper surface of the vertical outer portion d@ ofthe horizontal arm Eil; and the lower portion of this cylinder isarranged in a vertical opening il in the vertical arm portion li, asshown in Fig. 4. Contained in the vertical cylinder is a series ofcylinder and piston sections e8, i9 and 5B, herein arranged intelescopic relation and each having a piston portion and a tubularpiston rod portion. Reciprocable in the bore 5l of the inner Section 50is a piston E2 having a piston rod 53.

A return conduit |28, also passing through the arm2li, connects the passage |25 with the suction conduit |l. Hand operatedvalves |29 and |30, herein of the end-seating type, independentlycontrol the communication of the passage |25 with the end chambers |23and |26 respectively.

The conduits H1 and ||9 and |25 may have flexible portions (not shown)which extend outward from the arm 28 near its swivel bearing so that thearm may swing without interfering with the conduits in an obviousmanner. So that fluid may flow to the lower end of the cylinder l5beneath the pistons of the elevating jack Hl, the piston element 48 hasvertical passages 31 in the piston head thereof, permitting ow from thecylinder bore at the upper side of the piston head to the cylinder borebeneath the piston head. The walls of the several piston rod elementsare perforated at |32 to preclude trapping of fluid that may leakpast-the several piston heads into the upper ends of the severalcylinder bores. A

suitable shield or housing |33 encloses the fluid cylinder 56 and thevalve device H8 and is provided with side openings to permit access tothe handles of the hand valves |29 and |30. When the hand valves |29 and|36 are closed, fluid may flow, under the control of the slide valves il l and ||2, through conduits Hl and H9, through the end chambers |23and |25 of the valve device l I8, and thence through conduits 25 and |21to the elevating and floor jacks. When the slide valves Hl and i|2 arereturned to neutral position, the check valves |25 and i2i automaticallyprevent reverse fluid flow from the elevating and floor jacks, and whenthe valves |29 and |35 are opened, the elevating and floor jackcylinders are connected to the suction side of the pump through passage25 and conduits |28 and ici, to thereby effect rapid retraction of theelevating and floor jacks. Thus, the valve device HS may serve to ventthe jack cylinders and the valves 29 and I3@ thereof are normally closedduring operation of the jacks. Extension of the jacks is controlled bythe slide valves i l l and i i2 and the automatic check valves 42S and|2| serve, by precluding reverse iiow, to lccs: the jacks in extendedposition when the valves El and H2 are returned to neutral position.Evidently, the valve device i |23 may be constructed to vent the jackcylinders in other manners, as for example, directly baci; to the liquidreservoir.

The general mode of operation of the improved timber setting machine isas follows: The body compartment 8 is loaded with mine timberingelements, such as cross timbers and props, and the front roller guidedevice l2 may have its guide roller 19 positioned at the desired heightto facilitate loading of the timbering elements into the compartment.When the body compartment is loaded, the swingable support S and thetimber elevating and floor engaging jacks are moved to their transportposition shown in Figs. 1 and 2, and the motors 3, 3 may be operated todrive the traction wheels 2, 2 to effect propulsion of the machine alongthe mine passageways or tunnel. Steering of the machine is eiected bythe steering wheels 5, 5 under the control of the hand- Wheel 5. Whenthe machine is moving through a mine passageway or tunnel where there isno overhead trolley wire or other source of electric power, theconductor cable of the cable reeling mechanism I3 is attached to thetrolley wire or other power source in the main entry, and as the machinemoves inwardly toward the heading, the conductor cable-is pulled 01T ofthe reel with the cable under suitable tension. When the working face ofthe heading is reached and it is desired to set a cross timber, thetimber support or saddle I is turned with the piston rod 53 about thevertical axis of the elevating jack ||l to a longitudinally extendingposition, as shown in Fig. 3, to receive a timber moved lengthwise fromthe timber compartment, and the transverse guide roller is adjustedvertically in the compartment to the desired height, thereby properly toreceive the timber so that the latter may be easily moved outwardly ontothe timber support Il. The timbers are usually piled up on top of oneanother in the compartment, and the guide roller 8B may be positioned toreceive and guide a timber piled at any height. When a timber ispositioned centrally on the timber support ll, the jack lil may beoperated under the control of the slide valve to raise the timbersupport or saddle slightly above the machine body and the timber maythen be turned with the saddle about the vertical axis of the elevatingjack into a position crosswise of the machine body, as indicated indotted lines in Fig. 15. With the pump driving motor l running to causethe pump lill! to supply liquid under pressure to the valve box |54, theslide valve lill may be moved to a position to supply liquid underpressure to one end or the other of the arm swing cylinder 33 to swingthe arm 2&3 horizontally about its pivot to the desired position withrespect to the rear end of the machine body (one lateral position of thearm being shown in Fig. 16), and the slide valve H5 may thereafter bepositioned to trap the liquid in the cylinder 33, rigidly to lock thehorizontal arm 25 in adjusted position. The slide valve may then bepositioned to supply liquid under pressure past theA check valve |25 andthe valve device i3 (it being understood that the valves |29 and i351are at this time in closed seated position) to the cylinder 45 of theelevating jack ill to move the jack sections 48, 59, 5E) and 53 upwardlyto elevate the saddle to bring the cross timber supported thereby upagainst the roof (see Figs. 14 and 15), and the check valveautomatically traps the liquid in the elevating jack when the slidevalve i is returned to its neutral position. The slide valve |2 may thenbe positioned to supply liquid under pressure past the check valve l2|and the valve device I8 (with the valves |29 and |35 still closed) tothe upper end of the cylinder 55 of the iioor engaging jack to lower thefootpiece 'ill into firm engagement with the floor. The check valve |2|traps the liquid in the floor jack cylinder when the slide valve ||2 isreturned to neutral position to lock the jack piston in position. Theelevating jack holds the cross timber firmly in position up against theroof during setting of the uprights or props, or during insertion of therib pins. The elevating jack lf3 is suficiently powerful and is sorigidly braced by the door engaging jack that a cross timber may be rmlyheld in place during setting thereof even when a loose roof or rooffalls are present, and accidental dropping of the timber due to collapseof the elevating jack is prevented by the check valve |25 in the eventthe liquid supply should fail for any reason. When the valves |29 andE35 of the valve device ||8 are opened, liquid is discharged from thejacks through the passage |25 and the conduit |28 connected to theconduit Vlill leading to 9; thesuction sideioftjhe pump.; and-,dueto tbesuction created .within the elefr/ating,|-jaol, cyling dorsy the, jocksare rapidly. collapsed; Thoooriiig Hiv aids `in the retraction ofv4 thefioorjack piston, anduholds retracted thev fpotpiece..10 vWhen thesupporting arm.20and theeleyating andoorlen; gaging jacks have beenreturned to theirgtransport-positimshownv in Figs, 1 v and; 2 thedriving motors 3, 3.foi the trooiiori Wheelomoy'bo-rof versed. to propelthemachine outkvy/arldly,vawr/ay` from `the Working face, and astliemaehineinovle's' forwardly, the, hydraulic motoriY i3 drives. thecable reel I3 in the direction towind the con; ductorcable. in a Wellknown.:rnauri-r1e1gv As L.described inthe applicationabovefreferred'to,ltne power saw.
